ترجمة الملخص

Intramammary infection is defined as the presence and multiplication of a bacterial population inone or more areas of the udder. This disease has negative economic impacts.Our study aims to startwith, first of all, to identify the different bacteria that cause breast inflammation, and to determinethe frequency of the germs responsible for these infections. In a second step, estimate theimportance of clinical and subclinical mastitis and highlight the different factors that may increasethe risk of intra-mammary infections. The somatic cell count showed strongly elevated averagelevels, ranging from 160,000 to 680,000 cells / ml in the tested milks. The infection affects muchthe hindquarters (95%) compared to the forequarters (5%) with a predominance of breast-bornegerms (Staphylococcus aureus Fecal Streptococci) compared to environmental germs(Enterobacteria) that are absent.Par ailleurs, la présence de spores butyriques est constatée dansl’ensemble des laits des vaches litières des éleveurs et des collecteurs. Enfin, la prévalence desmammites est de 18,5% chez les vaches des éleveurs encadrés par les collecteurs et de 14,3% chezles vaches des éleveurs non encadrés.The poor hygienic conditions of milking, the non-control ofthe state of hygiene of the milking machine and the poor maintenance of the habitat, are probablythe risk factors for the appearance and the persistence of infections.
